Re: [OMPI users] config: gfortran: "could not run a simple Fortran program"

[Jeff Squyres (jsquyres) via users]

What is the exact configure line you used to build Open MPI?  You don't want to 
put CC and CXX in a single quoted token.  For example, do this:

./configure CC=gcc CXX=g++ ...

Don't do this (which is what your previous mail implied you might be doing...?):

./configure "CC=gcc CXX=g++" ...

This allowed gfortran to compile (and run) and then I was able to configure 
openmpi (4.1.0).
I am still trying to configure openmpi with gcc and g++ (as opposed to using 
clang and c++).

Thanks to all

Anthony,

Did you make sure you can compile a simple fortran program with
gfortran? and gcc?

Please compress and attach both openmpi-config.out and config.log, so
we can diagnose the issue.

Cheers,

Gilles

Gfortran (and gcc) is from High Performance Computing for OSX

Any clues will be gratefully received! And I apologize if this is a solved

Many thanks, Tony Rollett
PS.  If I try “CC=gcc CXX=g++” then it fails at the C compilation stage.

Anthony,

Did you make sure you can compile a simple fortran program with
gfortran? and gcc?

Please compress and attach both openmpi-config.out and config.log, so
we can diagnose the issue.

Cheers,

Gilles
